FEATURES

Energy saving
z
High energy saving was realized by making the indoor unit and outdoor unit fan motor and
compressor all DC and optimal design of the refrigerant cycle.
Quiet operation
z
Air ow mode can be set in 4 steps and more detailed air ow setting is possible.
45 type: 34 dB at operation in the Quiet mode.
Filter sign
z
Dirtying of lter is detected by air conditioner operating time and the user is informed.
Economy operation
z
The power consumption can be reduced.
Wired/wireless simultaneous use possible
z
Wired remote controller and wireless remote controller can be simultaneously used.
Flexible installation
z
A high installation of the
construction of the ceiling
and degree of freedom
corresponding to height is
possible.
Double auto swing
z
Combination of up/down and right/left air direction swing allows three-dimensional air direction
control.
Since up/down air direction aps operate automatically, according to the operating mode of the
unit, it is possible to set the air direction based on the operating mode.
